LFSF - first of all well done on shifting 16st around a half marathon course in 1:40, and the other times are pretty good too. Looks like you were aiming for about 2 x 1:50 for your first marathon but found you'd couldn't keep that pace up in the second half. There is a lot to learn about marathon running and people don't generally get anywhere near their potential at the distance until about their sixth one.
I'm concerned you seem to have multiple, very challenging targets for a relative newcomer to long distance running and one overweight at that! You seem to want to push the distance out very quickly, perhaps too quickly?
I'd say stick to the marathon for the time being and get nearer to achieving what you want with that distance first. Ultras will still be there when you want them - in fact ultrarunning is a fast growing sport and there are more new events every year.
If you do your marathon flat out then I'm not sure you're going to recover well enough and your ultra might be a disappointing experience (i.e. a lot of walking!) which you don't want for your first.
Agree with seren about colds, except I think you mean, seren, 'still above the chest = OK'!
All the best whatever you do. Yours is an inspiring story.
